I'm not that type of musician where I can sit down at the piano and work out a song; I actually really enjoy that process of sitting with somebody and having nothing and then suddenly something starts appearing. You struggle with it, and then suddenly a song starts to appear. Then, you've got to try and muscle it - there's that word again - into something and you do. You tussle with it and play with it and roll around with it and suddenly, magically, something appears.
